My new laptop (Asus N55SL) has a built-in wireless-n 1030 adapter. I'm using a Netgear DGND3700 Dual-Band router which is already being used by a few devices (via the g and n networks) so I know my router is working fine.

Both wireless bands are broadcasting their SSID.

My new laptop does not detect the n network. It can see the g network fine. I've even tried manually adding the n network with no result.

I've checked adapter properties and they are set as the following:

802.11n Channel Width for band 2.4 - Auto

802.11n mode - Enabled

Ad-Hoc channel for 802.11b/g - 11

Ad-Hoc QoS mode - WMM enabled

Bluetooth AMP - disabled

Fat channel intolerant - disabled

Mixed mode protection - CTS-to-self Enabled

Roaming aggressiveness - 3. Medium

Transmit power - 5. Highest

Wireless mode - 3. 802.11 b/g

I think the last 2 are for when I wish to use my laptop as a wireless station (?).

Everything looks like it should be able to connect to an n-network but it can't.

Buy a laptop that has the "802.11a" or "802.11ac" on their specs. For example, the Intel Centrino Advanced-N 6205 has this specification: 802.11a/b/g/n. If you see the letter "a" before "b" it means it has 5 GHz capability. follow this thread for more information: https://communities.intel.com/message/220265#220265
